Searcher Seismic has completed the regional multi-client airborne gravity, gravity-gradiometry and magnetics survey over the Gulf of Papua.
Covering about 60,700km² along the southern coast of Papua New Guinea (PNG), the Roho Airborne Gravity, Gravity-Gradiometry and Magnetic Survey complements several marine seismic and geochemical projects that were recently completed by the company.
The projects are aimed at assessing the hydrocarbon potential of the Gulf of Papua and adjacent Coral Sea areas, offshore PNG.
As part of the survey, the majority of the area covered comprised of shallow water transition zone environments.
CGG Multi-Physics acquired the survey using a Basler BT-67 and a DHC-6 Twin Otter twin-turbine fixed-wing aircraft.
The data was acquired with a 1km line spacing in the northern Gulf of Papua, and 2km line spacing extending along the coastline to south-east PNG.
In October 2017, Searcher Seismic announced plans to begin an airborne gravity, gravity-gradiometry and magnetics survey over the Gulf of PNG.
Searcher Seismic geoscientist and Asia-Pacific sales manager Andrew Weller said that the survey was designed to bridge the gap between the onshore areas of PNG with the offshore regions in the Gulf of Papua and the Coral Sea.
The Roho Survey provides a coherent dataset to the exploration industry over a significant portion of the Gulf of Papua’s transition zone environment and complements Searcher Seismic’s existing 2D seismic coverage.
The existing seismic currently stands at more than 87,000km, 3,888km² of 3D and a geochemical survey, offshore PNG.
Final data is currently available for the Roho Survey and a regional interpretation of the new data is set to be made available by next month.
